IPC: B65G60/00
Filed: 1988-05-07
Abstract: PURPOSE:To prevent the breakage due to the shock during the transfer of a tray by allowing a transfer device of a tray feeding stocker to detect the lowering by the thickness of a piece of the tray and allowing a clamp to clamp the tray in the next stage from the side parts. CONSTITUTION:When a transfer device 15 is raised up to the contact with the lowermost stage of a plurality of trays stored in a feeding stocker 6, a photosensor(PS) 23A is light-shielded at a detection point 26, and a lamp timing PS25A is light-shielded at a detection point 27.

Title: Indoor device of air conditioner
Inventor: ISONO KAZUAKI
IPC: F24F1/00
Filed: 1990-04-26
Abstract: PURPOSE:To keep a temperature around feet high and make an environment having no feeling of draft by a method wherein when a temperature of a main heat exchanger is higher than a predetermined reference temperature, a main air blower and a sub-air blower are operated and in turn when the temperature of the main heat exchanger is lower than the predetermined reference temperature, only the main air blower is operated. CONSTITUTION:During a heating operation, a temperature Tc of a main heat exchanger 33 detected by a heat exchanging temperature sensor is compared with a reference temperature T2. If a relation of Tc>=T2 is attained, indoor air sucked through a suction port 31 by a main air blower 37 and a sub-air blower 36 is heated by a sub-heat exchanger, divided into one sucked into the sub-air blower 36 and the other sucked into the main air blower 37. The former is blown out of the sub-blowing port 38 and the latter is further heated by the main heat exchanger and blown into a room through the main air blowing port 39. Due to the fact that air A having a low buoyancy is blown in parallel with air B having a high buoyancy, the blown air B is restricted in its ascending operation, resulting in that the air reaches a floor surface to increase a temperature around feet and the air A is already heated and there is no feeling of draft. If a relation of Tc<Ta is attained, the indoor air is heated by the main heat exchanger 31 under an operation of only the main air blower 37 and then blown into the room. At this time, a buoyancy of the blown air is low and the air can reach the floor surface and there is no feeling of draft.
